Is this nutrient burn or simply damaged leafs?

[DDG]

Hello.

I am working with my first grow and I switched to 12-12 at the 13/7, I have had some issues primarily a deficiency of macro nutrients which have lead me to increase the base nutrients step by step.
I use the PH of the run-off to judge the nutrient requirement and it was only during the last watering that I got the run-off PH down below PH 7,0. It was PH 6,7 after the last watering which makes me want to again water with identical amounts of nutrients in the hope that the PH will continue to drop.

But look at the below pictures, I have never seen nutrient burn so I don't know, however I have to add that I have during the past few days worked for several hours LST'ing quite aggressively to position the growth tips in there optimum position in terms of even canopy and even space for each and it is perfectly possible that I have inflicted these damages my self. But the plant needs water today and I really want to add nutrients if this is not nutrient burn:








Kind regards

U goin wrong way about feeds man. U dont need be checkin the run off ph to determine the feed.dark green an slow bud production with early browning/burning of pistils will indicate it bein thrown to much feed

This in soil or coco?
